Dear Forum,Does QCAD have a limit to the length of arcs?I am having some trouble making qcad-pro draw very long arcs. Here is the situation: I draw a square with sides measuring, say, 2,000,000 units (inches). Then, using the Arc by 2 Points with Angle Tool, I use the mouse to draw a 90-degree arc from one corner to the opposite corner. The result: qcad starts to draw the arc, but the arc disappears midway to the other corner. I draw arcs just fine with dimensions under a million units. I am using QCAD 3.4.7 on Mac 10.6.8.
